I have a strange issue where I cannot connect to SMB shares via the servername of my TrueNas server. It shows up on my windows clients just like my other servers, but if I double click to connect it throws a windows networking error saying “Windows cannot access \MyTrueNasServer” error code 0x80070035. So the TrueNas servername is visible in the windows network, however it is not accessible.
Further investigation - using cmd and ping - Ping request cannot find host MyTrueNasServer
I can connect - by using the \{server ip addr}. I have full SMB functionality from there.
I do have other NAS servers on the network which resolve fine via the SERVER_NAME and SMB works fine.
Note: I have a test laptop that produced the same symptoms until as part of my Univention server testing I changed it’s DNS server to the Univention server instead of my pfSense gateway/router. I don’t know how that changed anything since the Univention server does not as yet maintain any information about my TrueNas and neither Truenas or Univention are configured to recognize each other on the network or rely on services from the other.
Any ideas on how to troubleshoot this?
TIA
